When you use Thesis Navigation Bar and present links to categories & pages, there is no option to sort the links. Unfortunately I could not find a way to do that in one admin interface and there is no way to combine the sort between pages links and categories…

Install the category order plugin - drug & drop your categories to sort in the preferred order (under posts–>category order)
How to sort categories before pages in Thesis navigation menu?
